The primary obj ectof the present invention is to provide a novel and improved attachme'rit for corn planter which will permit the planting of .corn in transverse ialignment regardless of the contourof the 'groundso 'that corn m-ay-be eross- -1cultivated during -thecultivation pe d I Another object Ofathe invention 0 provide 'anovel and improved eonstruction "'oif oppositely disposed wmarker'flwheels :supported on skids or sleds; These skids-tor sledsare fioating'ly con- .the groundand' at the same time aeouratelyspace the hills "in transverse alignment.- a l "Theseland other objects 'are aeeomplished' h'y 2o nected to the main frame 'of the. planter. sg tl'ieit V the same will ride overthe uneven icon'tour of v providing a construction and anfiarrangeinent i Fig, 2 is a side elevationalview of a fragmentary portion of the corn planter- *showing the're1- ative position of my-improved planting attach- :ment supported thereon; and

The

corn planterin this instance-comprises the usual main frame l it which is supported in the-conventional manner by the usual'earrying wheels i l.

Theplanter in thisinstance is provided with the usual seed sans" 12 01 which there is onedecated on eachside of the rnachine." The *seed'can is also provided with a conventional seed feeding mechanism net shoWnl-whichin turn, is controlled or tripped by the usual trip -lever l3. l'For a more detailed description of :the fpianter conj'I'he' marker wheels ners 25 which have their front struction," see my eopentling application -pr viously -referred to. r

Myiimproved planter attachment comprises an inverted U-"shaped frame member M1 supported at the rear 'of'and from the main frame [0 of the -planter. The frame member 'EWhas depending-legs M; Dhe opposite ends of the LI-shaped frame member [4 =are'provided'with bearing supports l'5 "in whichis journaled atransvers'e shaft 16. The shaft 16 extends laterally beyond each "ofthe supporting wheels H of the planter and is provided with spaced apart apertures as shown -at |'-'l. Adjustably secured :to the outer ends of tlreshaift' 46 are marker wheels I78. The marker -wheelsrlfi 'are'provided With hubsfis through -Whieh a pin 20 is "adapted to secure: the marker wheels 'in the various -pesiti'onsindiated by 'tlie apertures I! onthe shaftforvarying the distance transversely [between the rows of corn planted.

V 1a are provided with radially projecting prongsQorr'od'sfll: Positioned at the diametrically opposite sides 'of thewheels 18', or

atd-SU intervals, are additional-prongs as indi- H These three prongs Iria'ke distinguishing marks in returntr'ip of the planter, the marker "wheel may 'be brought into alignment with the previously made marks-for aligning" or planting the corn in transverse rows; V

In operati'om the shaft t6 and itsrmarkerwheels 18 are supported on opposite skids or sleds generally indicated by the reference character" 24.

'Eachof these skids or sleds '24 comprise twolaterally spaced apart longitudinally extendin runand rear ends These runners each ;other by front and rear arch members 27 and 28, flxtending from each of'the rear arch fmenibers; 2-1 to the inverted U-sh'aped frame frnernber 1'4 are diagonal braces '29. ends of these diagonal .br

The *inner aces 29' may beadjusted to various apertures 3i! so as to accommodate the adjustment of the runners 2 3 when they are mqved outwa-rdly or inwardly for chan'g ing the distances between the rows of corn planted. The forward end of the runners 2 4are floati ngly. supported with respect to the main frame Hi: of the' cornp1anter by their lower ends connected to theforward arch members 26 and their upper ends slidably connected inflapertures formed in the outer ends of each of the brackets 32. The inner endsfiof ft-he hrackets '3 2 are secured to the main frame member-likes shown at "33. "Mounted on one the ground so that on the withrespect t0 rods'ti which have which are journaled rollers 46. cent the bracket M- is a plate48 which in turn is provided with a plurality of uniformly spaced drawings. A stop secured to the frame member l4 extend laterally in the pathof the'lever and limits the movement to the position shown" in Figs. 1 and 2 of the drawings.

- end of the trip lever 35 is connected by means of a rod 4| to the upper end'of the trip lever 13 of the seed feeding mechanism; Carried by and embracing the shaft [6 is a roller bracket The upper and the other end of the spring, as shown 42 which is preferably supported in position on the shaft by a cap through the mediumof bolts or rivets 44; Thebracket 42. has oppositely disposed arms 45 in the bifurcatedportion of Positioned adjaapart oppositely arranged apertures 5.9. These apertures 49 are located adjacent the periphery of the disc 48 and are adapted to receive bolts 50 for adjusting and securingthe roller trip with respect to the disc; 43. The disc 48 is provided with a hub 5! through the medium of which 'a bolt or pin 52 secures the disc 48 to the shaft i6. .The planter attachment, which includes the frame I l and its associated parts, is adjustedv with respect to th planter frame proper w by means of a lever 53. The lever 53 is provided with the usual detent mechanism generally indicated by the reference character 54. This detent mechanism is adapted to engage -notches 55 or 56 .located ina seotor' Sl for supporting theattachment in operative position or in transporting position. Thesector 51 is secured to the -main frame [0 of the planter. The lever 53'is secured by means of apin 58 to a transverse shaft 59.

, The shaft 59 is journaled in oppositely disposed be rings 60 carried by the mainfram'e ldr Se- 7 cured to the outer ends of the shaft 59 are rearwardly projecting cranks 6!. The outer or free 'endof the cranks 6f are provided with hooks 62 to which the upper ends of lift chains 63 are connected. The lower ends of the chains 63 ."areconnected to eye bolts 64, which in turn are connected adjacent the opposite ends of the frame member M of the planter attachment.

"Summarizing the novel features of operation V @as well as the advantages of my invention; it will be seen by providing 'a planter attachment for corn planter consisting of a frame floatingly supported from. the main frame of the planter on skids located on each side'of and to the krear of the planter proper. and having marker wheels thereon. so that the prongs thereof projept below the runners oftheskids'to effectively and accurately space off the distance between the tipping of the seeding mechanism, an accurate planting of the corn in transverse alignment is accomplished. r

It will also "be obvious that manipulating the lever 53Kforward1y and engaging the detent mechanism in the forward notch 56 of the sec torbl, the attachment may .be'raised to ftransporting position. However, when the lever is returned to the position shown .in Figs. land 2 of the drawings; the planting attachment frame i t e at l u ed w hi s s 9 1 main frame H3. As the corn planter moves forwardly, the prongs 2| of the marker wheels l8 located on each side of the planter proper, willengage the ground so as to accurately space'the distance between the hills planted. Obviously,

the three prongs or markers indicated by'the reference character 22 and located 180 apart onthe marker wheels, leave anidentifying mark i v in the ground sothat on tl'ielreturn travel of j i ;the planter, the-marker wheels m'ay be adjusted j to register with the previously made marks.

the trip with respect to the marker wheels either for correction, oriotherwise, the roller bracket {32 may be adjusted with respect to the I disc 48 for accomplishing thispurposeu r secure byLetters Patent is: q
